Arduino UNO 3.3V output

Dear Members,

I'm using Arduino UNO to configure my ADC chip via SPI but the output clock and data from the Arduino is 5V and I need 3.3V to configure my chip. Can anyone suggest me the solution for this?


cd74HC4050 48 cents, will drive your signals nicely. Probably need to drive chip select with 3.3V also?

For MISO coming back, use 1 gate of a 74HC125, powered from 5V, with it's OE controlled by the ADC chip select line (active low) 46 cents Will provide nice clean 0/5V signal back to the Arduino.
